To maintain a healthy swimming pool, the chlorine level in the pool should be maintained between 1.0 to 3.0 parts per million. The ideal level of chlorine in a swimming pool is dependent on several factors, including water temperature, number of swimmers, frequency of pool usage, rainfall and the pH level of the pool water.
Chlorine tablets that can be placed in floating and automatic feeders are the most popular pool chlorine treatments sold at pool supply stores. They are quite easy to use and can be instrumental in maintaining the optimal amount of chlorine in a swimming pool. For best results, it is a good idea to use chlorine tablets that dissolve at a steady rate as opposed to those that crumble easily.
